Dilation is the process of making something scaled. In the rectangle with a length of 4 and a width of 2, there is no dilation.
<h3>What is the rectangle?</h3>
A rectangle is a quadrilateral whose opposite sides are parallel and are of equal measurement.
<h3>What is dilation?</h3>
Dilation is the process of making something bigger or wider or scaled.
As we have the length of the rectangle as 4 and the width of the rectangle as 2, which is the same as before as well. therefore, there is no change in the length or the breadth of the rectangle. Thus, we can say that there is no dilation in the length and breadth of the rectangle.
Hence, In the rectangle with a length of 4 and a width of 2, there is no dilation.

Answer:
3600 ways
Step-by-step explanation:
person A has 7 places to choose from :
→ He has 2 places ,one to the extreme left of the line ,the other to the extreme right of the line
If he chose one of those two ,person B will have 5 choices and the other 5 persons will have 5! Choices.
⇒ number of arrangements = 2×5×5! = 1 200
→ But Person A also , can choose one of the 5 places in between the two extremes .
If he chose one of those 5 ,person B will have 4 choices and the other 5 persons wil have 5! Choices.
⇒ number of arrangements = 5×4×5! = 2 400
In Total they can be arranged in :
1200 + 2400 = 3600 ways
